                            MEETINGS OF STOCKHOLDERS

      Section 1. Time and Place of Meetings. All meetings of the stockholders
for the election of directors or for any other purpose shall be held at such
time and place, within or without the State of Delaware, as may be designated by
the Board of Directors, or by the Chairman of the Board, the President or the
Secretary in the absence of a designation by the Board of Directors, and stated
in the notice of the meeting or in a duly executed waiver of notice thereof.

      Section 2. Annual Meeting. An annual meeting of the stockholders shall be
held at such date and time as shall be designated from time to time by the Board
of Directors, at which meeting the stockholders shall elect by a plurality vote
the directors to succeed those whose terms expire and shall transact such other
business as may properly be brought before the meeting.

      Section 3. Special Meetings. Special meetings of the stockholders, for any
purpose or purposes, unless otherwise prescribed by law or by Certificate of
Incorporation, may be called by the Board of Directors, the Chairman of the
Board or the President, and shall be called by the President or the Secretary at
the request in writing of stockholders owning a twenty percent (20%) interest of
the entire capital stock of the Corporation issued and outstanding and entitled
to vote. Such request shall be sent to the President and the Secretary and shall
state the purpose or purposes of the proposed meeting.

      Section 4. Notice of Meetings. Written notice of every meeting of the
stockholders, stating the place, date and hour of the meeting and, in the case
of a special meeting, the purpose or purposes for which the meeting is called,
shall be given not less than ten nor more than sixty days before the date of the
meeting to each stockholder entitled to vote at such meeting, except as
otherwise provided herein or by law. When a meeting is adjourned to another
place, date or time, written notice need not be given of the adjourned meeting
if the place, date and time thereof are announced at the meeting at which the
adjournment is taken, provided, however, that if the adjournment is for more
than thirty days, or if after the adjournment a new record date is fixed for the
adjourned meeting, written notice of the place, date and time of the adjourned
meeting shall be given in conformity herewith. At any adjourned meeting, any
business may be transacted which might have been transacted at the original
meeting.

      Section 5. Quorum. The holders of one third of the stock issued and
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by law or by the
Certificate of Incorporation. If, however, such quorum shall not be present or
represented at any meeting of the stockholders, the stockholders entitled to
vote thereat, present in person or represented by proxy, shall have power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or represented.

      Section 6. Voting. Except as otherwise provided by law or by the
Certificate of Incorporation, each

                                       1
<PAGE>

stockholder shall be entitled at every meeting of the stockholders to one vote
for each share of stock having voting power standing in the name of such
stockholder on the books of the Corporation on the record date for the meeting
and such votes may be cast either in person or by written proxy. Every proxy
must be duly executed and filed with the Secretary of the Corporation. A
stockholder may revoke any proxy which is not irrevocable by attending the
meeting and voting in person or by filing an instrument in writing revoking the
proxy or another duly executed proxy bearing a later date with the Secretary of
the Corporation. The vote upon any question brought before a meeting of the
stockholders may be by voice vote, unless the holders of a majority of the
outstanding shares of all classes of stock entitled to vote thereon present in
person or by proxy at such meeting shall so determine. Every vote taken by
written ballot shall be counted by one or more inspectors of election appointed
by the Board of Directors. When a quorum is present at any meeting, the vote of
the holders of a majority of the stock which has voting power present in person
or represented by proxy shall decide any question properly brought before such
meeting, unless the question is one upon which by express provision of law, the
Certificate of Incorporation or these bylaws, a different vote is required, in
which case such express provision shall govern and control the decision of such
question.

                                   ARTICLE II

                                    DIRECTORS

      Section 1. Powers. The business and affairs of the Corporation shall be
managed by or under the direction of its Board of Directors, which may exercise
all such powers of the Corporation and do all such lawful acts and things as are
not by law or by the Certificate of Incorporation directed or required to be
exercised or done by the stockholders.

      Section 2. Number and Term of Office. The Board of Directors shall consist
of one or more members. The number of directors shall be fixed by resolution of
the Board of Directors or by the stockholders at the annual meeting or a special
meeting. The directors shall be elected at the annual meeting of the
stockholders, except as provided in Section 3 of this Article, and each director
elected shall hold office until his successor is elected and qualified, except
as required by law. Any decrease in the authorized number of directors shall not
be effective until the expiration of the term of the directors then in office,
unless, at the time of such decrease, there shall be vacancies on the Board,
which are being eliminated by such decrease.

      Section 3. Vacancies and New Directorships. Vacancies and newly created
directorships resulting from any increase in the authorized number of directors
which occur between annual meetings of the stockholders may be filled by a
majority of the directors then in office, though less than a quorum, or by a
sole remaining director, and the directors so elected shall hold office until
the next annual meeting of the stockholders and until their successors are
elected and qualified, except as required by law.

      Section 4. Regular Meetings. Regular meetings of the Board of Directors
may be held without notice at such time and place as shall from time to time be
determined by the Board of Directors.

the Secretary in like manner and on like notice on the written request of any
two directors.

      Section 6. Quorum. At all meetings of the Board of Directors, a majority
of the total number of directors then in office shall constitute a quorum for
the transaction of business, and the act of a majority of the directors present
at any meeting at which there is a quorum shall be the act of the Board of
Directors. If a quorum shall not be present at any meeting of the Board of
Directors, the directors present thereat may adjourn the meeting from time to
time to another place, time or date, without notice other than announcement at
the meeting, until a quorum shall be present.

      Section 7. Written Action. Any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee thereof may be taken
without a meeting if all members of the Board or committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes or proceedings of the Board or Committee.

      Section 8. Participation in Meetings by Conference Telephone. Members of
the Board of Directors, or any committee designated by the Board of Directors,
may participate in a meeting of the Board of Directors, or any such committee,
by means of conference telephone or similar communications equipment by means of
which all persons participating in the meeting can hear each other, and such
participation in a meeting shall constitute presence in person at the meeting.

      Section 9. Committees. The Board of Directors may, by resolution passed by
a majority of the whole Board, designate one or more committees, each committee
to consist of one or more of the directors of the Corporation and each to have
such lawfully delegable powers and duties as the Board may confer. Each such
committee shall serve at the pleasure of the Board of Directors. The Board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee.
Except as otherwise provided by law, any such committee, to the extent provided
in the resolution of the Board of Directors, shall have and may exercise all the
powers and authority of the Board of Directors in the management of the business
and affairs of the Corporation, and may authorize the seal of the Corporation to
be affixed to all papers which may require it. Any committee or committees so
designated by the Board shall have such name or names as may be determined from
time to time by resolution adopted by the Board of Directors. Unless otherwise
prescribed by the Board of Directors, a majority of the members of the committee
shall constitute a quorum for the transaction of business, and the act of a
majority of the members present at a meeting at which there is a quorum shall be
the act of such committee. Each committee shall prescribe its own rules for
calling and holding meetings and its method of procedure, subject to any rules
prescribed by the Board of Directors, and shall keep a written record of all
actions taken by it.

      Section 10. Compensation. The Board of Directors may establish such
compensation for, and reimbursement of the expenses of, directors for attendance
at meetings of the Board of Directors or committees, or for other services by
directors to the Corporation, as the Board of Directors may determine.

      Section 11. Rules. The Board of Directors may adopt such special rules and
regulations for the conduct of their meetings and the management of the affairs
of the Corporation, as they may deem proper, not inconsistent with law or these
bylaws.

      Section 1. Generally. Whenever by law or under the provisions of the
Certificate of Incorporation or these bylaws, notice is required to be given to
any director or stockholder, it shall not be construed to mean personal notice,
but such notice may be given in writing, by mail, addressed to such director or
stockholder, at his address as it appears on the records of the Corporation,

under the provisions of the Certificate of Incorporation or these bylaws, a
waiver thereon in writing, signed by the person or persons entitled to such
notice, whether before or after the time of the event for which notice is to be
given, shall be deemed equivalent to such notice. Attendance of a person at a
meeting shall constitute a waiver of notice of such meeting, except when the
person attends a meeting for the express purpose of objecting, at the beginning
of the meeting, to the transaction of any business because the meeting is not
lawfully called or convened.

                                    ARTICLE V
